Optimal Flexible Architecture

The Oracle9i Real Application Clusters Guard directory structure depends on the type of installation you perform when installing the software. This appendix contains the following sections:

Introduction to Optimal Flexible Architecture

Oracle Corporation recommends the Optimal Flexible Architecture (OFA) standard for Oracle installations. The OFA standard is a set of configuration guidelines for efficient and reliable Oracle databases that require little maintenance.

OFA provides the following benefits:

To switch to the OFA standard, you must modify the directory structure and relocate the database files.

See Also:

  • See the Oracle operating-system specific documentation for more information about OFA.

  • See the Oracle9i Administrator's Guide for information about relocating your database files.

 

OFA Compliant Installation

If the ORACLE_BASE environment variable is set during installation, an OFA installation is performed, and the PFS_HOME environment variable is set to
$ORACLE_BASE/admin/db_name/pfs.

The following is the directory structure of a sample Oracle9i Real Application Clusters Guard OFA compliant installation on UNIX platforms:

$ORACLE_HOME
$ORACLE_HOME/pfs
$ORACLE_HOME/pfs/admin
$ORACLE_HOME/pfs/admin/demo
$ORACLE_HOME/pfs/bin
$ORACLE_HOME/pfs/bin/oracle_up
$ORACLE_HOME/pfs/bin/oracle_ping
$ORACLE_HOME/pfs/bin/oracle_lsnr

Non-OFA Compliant Installation

If the ORACLE_BASE environment variable is not set during installation, a non-OFA installation is performed and the PFS_HOME environment variable is set to $ORACLE_HOME/pfs/db_name.

The following is the directory structure of a sample Oracle9i Real Application Clusters Guard non-OFA compliant installation on UNIX platforms:

$ORACLE_HOME
$ORACLE_HOME/pfs
$ORACLE_HOME/pfs/admin
$ORACLE_HOME/pfs/admin/demo
$ORACLE_HOME/pfs/bin
$ORACLE_HOME/pfs/bin/oracle_up
